Denver Basin bedrock
Confined sandstone aquifer; negligible human-timescale recharge — pumping is one-way storage mining.
Because this aquifer does not recharge on a human timescale, a decline here is storage being removed, not a stream being short. It is kept out of the stream-depletion math for that reason.
Water-level record
28 measurements from 2000-10-20 to 2002-09-30. Most recent water-level elevation 4741.37 ft, 1054.63 ft below ground.
Over the record the level is insufficient data . Mann–Kendall with the Hamed–Rao autocorrelation correction, on water-level elevation; rising elevation means more water.
Chart: water level at this well over time, 2000-10-20 to 2002-09-30, 28 measurements. The record is insufficient data (p equals None), measured on water-level elevation. Rising elevation means more water. The values are downloadable as CSV from the link above.

What this page is not
Monitoring records are irregular: measurements cluster where somebody chose to look, so a trend describes this well's record, not the aquifer as a whole. Levels are DWR's published measurements, unedited. A trend here is not a prediction, and it is not a determination about anyone's water right.
